I have a Garmin Streetpilot 7200 mounted on the left handlebar. I believe it is larger than your Iway 600C, and I really like it. I use it on the Goldwing and in my Silverado. It is not waterproof, so I carry a ziplock bag raincoat in the left pocket to protect the 7200 during rain.
The Garmin Zumo line is used by a lot of riders, along with other Garmin models.
I use a handheld Garmin 60CSx on my bikes and other vehicles. I have the latest version of Garmin Street Atlas North America. The screen is easy to view when the unit is mounted on the handlebars. It is powered from the bike's 12 volt system when riding and batteries when in the woods or geocaching. We do a lot of geocaching and the GPS is well suited for that purpose.
Garmin GPS478 Chart Plotter (no longer built) but looking for the next one to replace it. It's great and creates a log of speed, position, elevation, time etc... Any recommendations appreciated. Must be able to connect with computer and dump log file.
I agree. Fantastic GPS. Very accurate and easy to use. Can load 1,000 songs on the MP3 card. XM radio when you install the antenna. I bluetooth my phone. Then, can receive telephone calls and make calls while I am driving through the helmet headset/ mic. Designed for motorcycles by people who ride motorcycles.
I have the OEM Honda GPS on the 2010 but came across a deal I couldn't pass up last week which was the TomTom Rider 2 that a guy was selling for $100.00 with the mount, wiring, case, and Bluetooth headset all in perfect condition. Used it for a ride Saturday and it functioned very well. My only complaint really is that it is difficult to see in direct sunlight.
Are you interested in what do I use or what would I use? Not caring for what's on the bike, I borrow the kid's 550 Zumo for those (very few) trips where I need a GPS unit. That's what I would recommend.
I have a Garmin Quest2, which is no longet made. Waterproof, small, battery lasts 10 hours, works with Mapsource, and best of all, when the sun's shining on the screen, it reflects and actually shows the screen better. No music storage, no Bluetooth or audio hookup for voice turn by turn, but for me, simple is good and it works flawlessly. I'm probably the only one on the forum with one.
They still sell them and still do map upgrades for them. I've had it on my bikes since '07. Love it!
